* [aarch64-darwin] be very careful of warnings.Moritz Angermann2021-03-301-0/+1
| | | | | | | | | So we did *not* have the stgCallocBytes prototype, and subsequently the C compiler defaulted to `int` as a return value. Thus generating sxtw instructions for the return value of stgCalloBytes to produce the expected void *. (cherry picked from commit 273e1f6d6886eb226699071184bb25dd463e8f82)

* Allocate Adjustors and mark them readable in two stepsMoritz Angermann2021-03-3018-20/+90
| | | | | | | | | | | This drops allocateExec for darwin, and replaces it with a alloc, write, mark executable strategy instead. This prevents us from trying to allocate an executable range and then write to it, which X^W will prohibit on darwin. This will *only* work if we can use mmap.

* Fix the binder-swap transformation in OccurAnalSimon Peyton Jones2021-03-295-53/+234
| | | | | | | | | | | | The binder-swap transformation needs to be iterated, as shown by #19581. The fix is pretty simple, and is explained in point (BS2) of Note [The binder-swap substitution]. Net effect: - sometimes, fewer simplifier iterations - sometimes, more case merging (cherry picked from commit b7f5f8b54ab8fe3665ec2282b6b1403d5483cf0b)

* Move loader state into InterpSylvain Henry2021-03-2321-579/+649
| | | | | | | | | | | | | | | | | | The loader state was stored into HscEnv. As we need to have two interpreters and one loader state per interpreter in #14335, it's natural to make the loader state a field of the Interp type. As a side effect, many functions now only require a Interp parameter instead of HscEnv. Sadly we can't fully free GHC.Linker.Loader of HscEnv yet because the loader is initialised lazily from the HscEnv the first time it is used. This is left as future work. HscEnv may not contain an Interp value (i.e. hsc_interp :: Maybe Interp). So a side effect of the previous side effect is that callers of the modified functions now have to provide an Interp. It is satisfying as it pushes upstream the handling of the case where HscEnv doesn't contain an Interpreter. It is better than raising a panic (less partial functions, "parse, don't validate", etc.).
* rts: Use long-path-aware statBen Gamari2021-03-233-4/+11
| | | | | | | | Previously `pathstat` relied on msvcrt's `stat` implementation, which was not long-path-aware. It should rather be defined in terms of the `stat` implementation provided by `utils/fs`. Fixes #19541.
* PPC NCG: Fix int to float conversionPeter Trommler2021-03-231-6/+26
| | | | | | | | In commit 540fa6b2 integer to float conversions were changed to round to the nearest even. Implement a special case for 64 bit integer to single precision floating point numbers. Fixes #19563.

* Short-circuit warning generation for partial type signaturesSimon Peyton Jones2021-03-221-2/+28
| | | | | | | | | | | | | | | | | | | | | | | | This Note says it all: Note [Skip type holes rapidly] ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Suppose we have module with a /lot/ of partial type signatures, and we compile it while suppressing partial-type-signature warnings. Then we don't want to spend ages constructing error messages and lists of relevant bindings that we never display! This happened in #14766, in which partial type signatures in a Happy-generated parser cause a huge increase in compile time. The function ignoreThisHole short-circuits the error/warning generation machinery, in cases where it is definitely going to be a no-op. It makes a pretty big difference on the Sigs.hs example in #14766: Compile-time allocation GHC 8.10 5.6G Before this patch 937G With this patch 4.7G Yes, that's more than two orders of magnitude!

* Remove unnecessary extendTyVarEnvFVRn functionRyan Scott2021-03-213-11/+6
| | | | | | | | | | | The `extendTyVarEnvFVRn` function does the exact same thing as `bindLocalNamesFV`. I see no meaningful distinction between the two functions, so let's just remove the former (which is only used in a handful of places) in favor of the latter. Historical note: `extendTyVarEnvFVRn` and `bindLocalNamesFV` used to be distinct functions, but their implementations were synchronized in 2004 as a part of commit 20e39e0e07e4a8e9395894b2785d6675e4e3e3b3.
